I have bought a device on the strength of internet reviews and not googled the forums.
I bought the WD My Cloud 3 TB from Tesco on friday.
The first thing that happened was it updated its firmware to the lates release (4.0).
I wanted it to replace an old NG NAS that has served me well but is not great at media serving.
I started to copy a folder across from the NAS to the My Cloud and was taken aback by how slow it was, less than 800 GB was according to my Ubuntu desktop going to take more that 30 hours.
This on a gigabit wired network.
I copied a few hundred GBs across and left it till today.
I then copied a 10GB file from the My Cloud to the Ubuntu desktop. It was going to take 2 hours at 1.6MB/sec on a gigabit wired network.
I then copied the same file from my NAS that is only connected at 100Mb/s. It achieved 34.6 MB/sec.
According to the review on trustedreviews.com it should achieve around 92MB/sec.
I should have come here before buying and seen the problems others have been having for ages without any sign of an official fix.
I refuse to hack the firmware of a brand new device so if there is no likelyhood of a repaired firmware in the very near future then Tesco will be getting this box back as unfit for purpose.
